从另一个 function 调用leadingSwipeActionsConfigurationForRowAt

Question

An unusual question, I have a UITableViewCell that have both leading and trailing swipe actions,

Is there a way to call one from another?

For example the user swiped the cell and leading action appeared, on clicking on it, the trailing action will appear.

As in the attached photo here

When the user swipe an icon will appear from the leading edge of the cell, once clicked, the trailing action will appear with a confirmation button to delete the cell.

Is that possible to achieve?

Here is my code:

    func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let leadingAction = UIContextualAction(style: .normal, title: "", handler: { (leadingAction, view, completionHandler) in
        // Action here
        completionHandler(true)
    })

    if let deleteImage =  UIImage(named: "Delete")?.cgImage {
         leadingAction.image = ImageWithoutRender(cgImage: deleteImage, scale: UIScreen.main.nativeScale, orientation: .up)
    }

    let preventFullSwipe = UISwipeActionsConfiguration(actions: [leadingAction])
    preventFullSwipe.performsFirstActionWithFullSwipe = false


    leadingAction.backgroundColor = Colors.clearAlpha
    let configuration = UISwipeActionsConfiguration(actions: [leadingAction])
    return configuration
}

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let trailingAction = UIContextualAction(style: .normal, title: "", handler: { (trailingAction, view, completionHandler) in
        // Action here
        completionHandler(true)
    })

    if let deleteImage =  UIImage(named: "ComfirmDelete")?.cgImage {
         trailingAction.image = ImageWithoutRender(cgImage: deleteImage, scale: UIScreen.main.nativeScale, orientation: .up)
    }

    trailingAction.backgroundColor = Colors.clearAlpha
    let configuration = UISwipeActionsConfiguration(actions: [trailingAction])
    return configuration
}

You can simulate gesture of swipe by adding following lines in trailing action completion block

let gesture = UIPanGestureRecognizer()
gesture.setTranslation(CGPointMake(0, 100), inView: youtableViewCell)
wasDragged(gesture)

further behavior.

func wasDragged (gesture: UIPanGestureRecognizer) {        
    let translation = gesture.translationInView(youtableViewCell)
    let cell = gesture.view!

    // Move the object depending on the drag position
    cellcontentView.center = CGPoint(x: self.view.bounds.width / 2 + translation.x,
                              y:  self.view.bounds.height / 2 + translation.y)
}

Note: It may be not a perfect solution but you can make it work you have a guide now:)
